. MPLS-TP objectives:
. Enable MPLS to be deployed in a transport network and operated in a similar manner to existing transport technologies (SONET/SDH)
. Enable MPLS to support packet transport services with a similar degree of predictability and reliability to that found in existing transport networks
. MPLS-TP extensions are fully compatible with existing MPLS specifications and newly defined protocols are included in IETF MPLS set MPLS TP

. All OAM functionality needs to be in-band
. OAM packets are sent over the data plane
. Takes same path as the user payload
. No out-band signaling component
. OAM functionality must not depend on IP forwarding LSP
. ACh is used for OAM on all levels
. Using the PW-ACh for Pseudowires
. RFC 4385
. Using a Generic ACh (G-ACh) for LSPs
. RFC 5586 User data packets OAM packets LSP
. A dedicated channel associated with the data path is created for the OAM packets
. Known as an Associated Channel (ACh) Transporting OAM Packets

Transport-Like Resilience
Protection Switching Triggered by OAM
No dependencies on Signaling or Control Plane
.Comprehensive set of recovery mechanisms
.OAM triggered protection mechanisms are standardized within MPLS-TP
.Existing MPLS & GMPLS mechanisms may also be used
. Similar functionality across PWs, LSPs, SPMEs, and sections

summary
. Transport networks are under transformation
. MPLS-TP, OTN and P-OTP will enable the transport evolution with simplicity, efficiency and scalability
. MPLS-TP is MPLS.
. It is optimized for transport neworks paradigm
. MPLS-TP provides a similar degree of predictability, reliability and OAM to that found in existing SONET/ SDH transport networks
